Later thermionic vacuum tubes, mostly miniature style, some with top cap connections for higher voltages. A vacuum tube, electron tube, [1] [2] [3] thermionic valve (British usage), or tube (North America) [4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
Vacuum tubes which had special qualities of some sort, very often long-life designs, ... Has similar electrical characteristics as 1B3GT.
6N3C power tube. A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s.

However, more recently, vacuum tubes have been making somewhat of a comeback. Triodes continue to be used in certain high-power RF amplifiers and transmitters. While proponents of vacuum tubes claim their superiority in areas such as high-end and professional audio applications, the solid-state MOSFET has similar performance characteristics. [24]
In electronics, the 300B is a directly-heated power triode vacuum tube with a four-pin base, introduced in 1938 by Western Electric to amplify telephone signals. It measures 6.4 in (16 cm) high and 2.4 in (6.1 cm) wide, and the anode can dissipate 40 watts thermal.
6SN7 vacuum tube dual triode made by Raytheon. ... electrical characteristics to the 6SN7 and ECC32, and a filament usable on either 6.3V or 12.6V supplies, ...
The 6V6 is a beam-power tetrode vacuum tube. The first of this family of tubes to be introduced was the 6V6G by Ken-Rad Tube & Lamp Corporation in late 1936, [1] with the availability by December of both Ken-Rad and Raytheon 6V6G tubes announced. [2] It is still in use in audio applications, especially electric guitar amplifiers. [3]
